The perimeter of a triangle is 70 cm and its sides are in the ratio 2:3:5.Find the length of sides of triangle.

Given, perimeter of a triangle = 70 cm

and ratio of its sides is 2 : 3 : 5

Let the sides of a triangle be 2x , 3x and 5x.

Perimeter of triangle=2x+3x+5x

70=10x

So, the sides are 2x=2x7=14,3x=3x7=21

and 5x=5x7=35
